COAL-CHUTE.

To all whom 2'25 may concern:

Be it known that I, RALPH A. DYER, a citizen of the United States, residing at Bangor, in the county of Penobscot and State of Maine, have invented certain new and useful Improvements in Coal-Chutes;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to screening and grading chutes and has for an object to provide a chute of substantially the usual and ordinary form with a grading screen in the bottom of the chute and with improved means for catching the material passing through the screen.

A further object of the invent-ion is to provide a chute having an improved form of grading screen in the bottom with improved accessories and parts associated therewith.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings :Figure 1 is a perspective view of the improved chute with the receptacle applied thereto. Fig. 2 is an inverted plan View of the chute. Fig. 3 is a longitudinal sectional view taken on line 3-3 of Figs. 1 and 2.

Like characters of reference indicate corresponding parts throughout the several views.

The present invention is adapted to be applied to any ordinary form of chute 10 used for conveying any material as for instance coal and while it willbe described and discussed in relation to its use as a coal chute, it is to be understood that it is not limited to such purpose.

In the bottom of the chute an opening is provided extending transversely entirely across the chute and to compensate for the material so removed and strengthen the chute bracing strips 11 are rigidly secured Specification of Letters Patent.

to the sides 12 spanning the opening and extending far enough beyond the limit of such opening to be rigidly secured to such sides. Beneath the opening a screen is disposed made up of longitudinal bars or wires 13 preferably bent as at le so that such wires are flush with the inner surface of the bottom of the chute and secured. in any approved manner as by cleats 16 extending transversely across the bottom of the chute and secured thereto as by rivets 17 The extremities of the cleats 17 are extended to form hooks 18 upon which is hung a receptacle preferably comprising a fabric bag or basket 19 having a resilient metal frame terminating in loops or eyes 20 which may be sprung apart by employing the resiliency of the frame to hook upon the hooks 18. Upon the under side of the longitudinal bars or wires 13 transverse wires 21 are employed preferably having their ends turned up as at 22 and engaged under the bracing strips 11.

By the employment of the grading screen madein accordance with the disclosure the bottom of the chute is practically uninterrupted in its plane, the wires or rods extends ing upwardly flush with such plane to prevent any undue bouncing of material passing downwardly through such chute.

I claim 1. A chute comprising a plane bottom and vertical sides, cleats extending transversely across and extending beyond the sides of the chute and turned upwardly into hooks, wires extending longitudinally of the chute bound in position by the cleats and bent upwardly flush with the inner surface of the bottom, and other wires extending transversely across under the first mentioned wires and spaced apart.

2. A chute comprising a substantially plane bottom and vertical sides and provided with an opening cleats extending transversely across the chute at the upper and lower margins of the opening, such cleats extending laterally beyond the sides of the chute and turned upwardly to form hooks, wires extending longitudinally of the chute bound in position by the cleats, such the transverse wires between said cleats and Wires being bent upwardly to produce sursides. 10 faces substantially flush with the, inner sur- In testimony whereof I aflixnmy signature face of the bottom, other Wires spaced apart in presence of two witnesses.
